Techniques are described for controlling a sensing state of a device. In an example, a controller of the device stores, in a memory of the controller, first state data indicating a state of a sensor, the state being enabled. The controller, receives first input data indicating a request to disable the sensor. The controller determines that the sensor is enabled based at least in part on the first state data. Further, the controller causes the sensor to be disabled and stores, in the memory, second state data indicating that the sensor is disabled. The controller sends, to a processor, first output data indicating that the sensor is disabled.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
16. The device of claim 15, wherein the light source comprises a plurality of red, blue, green (RGB) light emitting diodes (LEDs), wherein the controller comprises a plurality of analog-to-digital converters (ADCs), wherein each ADC is coupled with a different RGB LED, and wherein an input signal is received by an ADC from an RGB LED.
This invention relates to a lighting device with a color-mixing system for adjusting light output. The device addresses the challenge of precisely controlling light color and intensity in LED-based systems, particularly for applications requiring dynamic color adjustments. The system includes a light source with multiple red, blue, and green (RGB) light-emitting diodes (LEDs) to generate a wide range of colors. Each LED is connected to a dedicated analog-to-digital converter (ADC) within a controller. The ADCs measure the electrical signals from the LEDs, allowing the controller to monitor and adjust the light output in real time. This feedback mechanism ensures accurate color mixing and intensity control. The controller processes the ADC inputs to regulate the LEDs, enabling precise color calibration and dynamic adjustments. The system is designed for applications where consistent and tunable lighting is required, such as displays, medical devices, or industrial lighting. The use of dedicated ADCs for each LED channel improves response time and accuracy compared to shared or digital-only control methods. The invention enhances color fidelity and reduces power waste by optimizing LED operation based on real-time feedback.
17. The device of claim 15, wherein the light source comprises a plurality of red, blue, green (RGB) light emitting diodes (LEDs), wherein the controller comprises an analog-to-digital converters (ADC) coupled with the RGB LEDs, and wherein an input signal is received by an ADC from an RGB LED.
This invention relates to a lighting device with color control capabilities, addressing the need for precise and dynamic color adjustment in LED-based lighting systems. The device includes a light source composed of multiple red, blue, and green (RGB) light-emitting diodes (LEDs) that can produce a wide range of colors by varying the intensity of each LED. A controller is integrated with the system, featuring analog-to-digital converters (ADCs) that interface directly with the RGB LEDs. The ADCs receive input signals from the LEDs, allowing the controller to monitor and adjust the light output in real time. This feedback mechanism enables accurate color calibration, ensuring consistent and desired lighting effects. The system may also include additional components, such as a power supply and a user interface, to facilitate operation and customization. The invention improves upon existing LED lighting solutions by providing enhanced color accuracy and adaptability, making it suitable for applications requiring precise lighting control, such as displays, medical devices, or industrial automation.
